WebMole fraction solubilities in methanol, ethanol and I-propanol have been measured by Niepel et aZ. (12) and in I-butanol and l-octanolby Gerrard (1). Mole fraction solubilities tend to increase with increase in chain length but the solubility in methanol is greater than that in ethanol. Ammonia shows a similar pattern of behaviour with anomalous WebStyrene [Benzene] groups are prone to ring opening. This is when the benzene ring breaks open and releases a fair amount of energy. ABS will not have this behavior, but it is good to do a test piece before address other styrene polymer eg. “High Impact PolyStyrene” [HIPS] Flexible Materials Silicone Bonds to other silicones.
